Music for All with Open Source Software
I am embarrassed to admit that I have never in my life considered the struggle of blind musicians to find Braille music scores. I did not realize until last week that only about 1% of sheet music is available in an accessible format, but my friend Robert Douglass is hoping to change that with his Open Well-Tempered Clavier - Ba©h to Bach project on Kickstarter.com.
To get a better idea of what the lack of Braille music scores means to an actual musician, see Eunah Choi's video below.
The Open Well-Tempered Clavier Kickstarter project began with the goal of creating a public domain score and recording of Bach's Well-Tempered Clavier, with the intention of making Bach's work, a cultural treasure, accessible to all without the burden of copyright. Along the way, Robert and the others behind this project discovered that full accessibility is a much greater challenge. While a public domain score and recording tears down a few walls, other walls remain for those can't see the score. To that end, the project's goal has now been extended to include a Braille version of the Bach score, and with enough funding, a means to convert tens of thousands of scores into Braille thanks to open source software.
The underlying issue is about creating a process whereby existing open source music tools can be made to work together properly, and then be used to generate Braille scores, as no open source tools yet exist for creating Braille music. The specific technical challenge will be to complete work on an open source Braille converter for the MusicXML format, which would then allow the 50,000 scores on MuseScore.com, and any future additions, to be downloaded as a Braille file that is then readable with a Braille terminal. MuseScore.com is a web service that facilitates creating, sharing, and storing sheet music using MuseScore's open source music notation software. As an interesting sidenote, MuseScore's popularity is on the rise compared to its proprietary equivalents (see the illustration of Google trends below), so score another point for team open source and for music educators as well.
While the initial funding goal of the Kickstarter project has been met, additional funding would allow for the additional software development necessary to take existing code from the Freedots project and, among other things, turn it into a viable and free web-service that would automatically convert MusicXML files to Braille.

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
